Find the first ICMP Echo Request message that was sent by your computer after you changed the Packet Size in pingplotter to be 2000. Q6) Has that message been fragmented across more than one IP datagram? If so, how many? Q7) What information in the IP header indicates that the datagram been fragmented? What information in the IP header indicates whether this is the first fragment versus a last fragment?

The IPV4 Header Header And Its Fields Are Given For Your Reference. Read the questions that follow the Header diagram.

The TTL behaviour for IP-to-Label or Label-to-IP connections is depicted in the below image. Ingress LSR receives a packet with a TTL value of 289 arriving. What would the TTL value be for the ingress and egress LSRs? the letters (A, B, C, D, E, F, G, and H). TTL = 289 MPLS Label IPv4 Packet Ingress LSR TTL = A: TTL = B: LSR TTL= C: TTL=D: X LSR TTL=E: TTL=F: Label Switched wh TTL= G: LSR TTL=H: Egress LSR
